Application filed July 1,

.Pin setting machines of the hand operated type are usually controlledby counterweights arranged in front of the setter frame and rising andfalling according as the frame is lowered or raised. The ob ect of myinvention is to provide a setter, par ticularlof the hand operated typereferred to in w ich the counterweight is replaced by a spring operatedmeans for returning the frame to its normal bed. x Another object is toprovlde a device of the above character composed of a minimum number ofparts and which shall be easily made and eflicient in operation;

In the accompanying drawings in which-I have shown a selected embodimentof my invention- Fig. 1 is a front elevation of my invention as appliedto an alley bed.

Fig. 2 is a sectlon taken on the line 2--2 of Fi 1, but drawn to alarger scale.

ig. 3 is a section on the line 3-3 of position above the alleyfieferring now to the drawings, I have shown at 1 an alley bed at thesides of WlllCll are placed posts 2 carrying cross-bars 3 and 4, theseelements forming a frame on which the machine may be supported.Carriedon the cross-bars 3 and dis a bracket 5 havlng thereon upstandingears 6 supporting bolts 7 and 8, which form pivots on which are mountedlevers 9 and 10 extending transversely of the alley bed.

The levers 9 and 16 are provided beyond their" pivots with intermeshingsegment gears 11 and 12, whereby the levers will move in unison. Pivotedat the ends of the lovers 9 and 10 are links 13 and 14 secured at theirlower ends to the setter frame, which I have designated generally as 15.This frame is of the type shown and described in my co-pendingapplication Serial No. 16,332, filed March 18, 1925 and for the purposeof the present application need not be further described. The frame isprovided with suitable guide rods 16 sliding in guide tubes 17, asdisclosed in my aforesaid copending application, this arrangementinsurmg movement of the frame in a vertical direction.

As well understood in the art, the setter frame is adapted to containbowling pins, which are placed therein when the frame is in the raisedposition, shown in Fig. 1 and rm-snrrmc autumn.

1925. Serial No. 40,727.

which are do osited on the proper spots on the alley be when the frameis lowered. Any suitable means may be provided for releasing the pinsfrom the frame. For the purpose of lowering the frame I provide thehandle 18 pivoted to the cross bar 4 by suit-- able arms 19 andconnected to the frame by links 20. I

The levers 9 and 10 are provided with hubs 21 and 22 respectively andformed intcgral with these hubs are arms 23 and 24 connected to links 25and 26 pivotally secured at their outer ends to rods 27'and 28 mountedto slide in cylinders 29 and 30 respectlvely. Surrounding rods 27 and 28are SPI'IIWS 31 and 32, the tension of which may be a justed by suitablemeans exemplified by the nuts 33 and 34 threaded on the ends of therods.

It is believed that the operation of the device Wlll be obvious from theabove description, but it will be briefly summarized as follows: Uponactuation of the handle '18 to lower the setter frame 15, the frame willpull downwardly on the links 13 and 14, thus causing the levers 9 and 10to rotate on the pivots 7 and 8 and compress the springs 31 and 32. Dueto the'intermeshing gears 11 and 12 the levers work in unison and theforce exerted by each spring is uniformly distributed to each of thelinks 13 and 14. After the pins have been set on the alley bed, thehandle may be released and the springs will then return the frame to itsuppermost position, as shown in Figs. 1 and 3. During this movement-eachspring will do its full share of work due to the intermeshing gears.Moreover, it will be evident that by the above arrangement a pluralityof small springs may be employed instead of one large spring.

From the above it will be apparent that I have provided a .novel andimproved pin setting machine which-will operate in an eificient mannerand which entirely eliminates the counterwei ht previousl used. Inactual practice I have found t at my machine is very satisfactory asregards manufacture, operation and maintenance. It will be seen t at thenumberof parts has been reduced to a minimum and that the cost of heavyexpensive springs has been avoided by the use of a plurality of springs,

so connected to the machine as to have all OI IUSKEGON, MICHIGAN,ABSIGNOB TO THIBBUNIWIGK-BLLIE- v ter frame, means son. While I haveshown the device used with a particular type of setter frame, it isobvious that it may be employed with any other type without requiringany substantial modification. The cylinders containing the springs maybe arranged in any desired position, but I have found the substantialhorizontal position, as shown in the drawings as being very advantageousin operation and moreover it will be seen from an inspection of Fig. 1that the cylinders are practically concealed from view behind thecross-bar 4 thereby adding to the apance of the device by avoiding thepresence of elements of the machine in a conspicuous place. A pinsetting machine is of necessity placed in a conspicuous position and anyarrangement of the parts thereof which will diminish its conspicuousnessis desirable. It will be evident that the arrangement which I havedevised achieves the above result. \Vliile I have shown my invention asbeing operated by compression springs, it is of course obvious thattension or other forms of springs ma be used if desired, all that isnecessary being an arrangement whereby a spring is stressed.

I am aware that changes in the form, construction and arrangement ofarts may be made without departing from t 1e spirit and withoutsacrificing the advantages of the invention and I reserve the right tomake all such changes as fairly fall within the scope of the folowingclaims.

I claim:

1. A pin setting machine comprising a setter frame, means to lower saidframe to set the pins, and a plurality of springs com prcsed by thelowering .of said frame and acting to raise the frame to its uppermostposition upon release of said lowering means.

2. A pin setting machine comprising a setto lower said frame to set thepins, and a plurality of springs compressed by the lowering of saidframe and means causing said springs to actin unison to raise said frameupon release of said lowering means.

3. A pin setting machine comprising a frame adapted to set the pins,means to lift said frame to its uppermost position and comprising aplurality of springs and a plurality of members connected to said frameand each member acted on by one of said SPI'IHTS.

' 4:. A pin setting machine comprising a setter frame, means to liftsaid frame and comprising a plurality of springs, a plurality of membersconnected to said frame and each member acted on by a spring, and meanscausing said members to move in unison whereby the action of saidsprings will be uniformly distributed to said members.

5. A pm setting. machine comprising a setter frame, means to lift saidframe and comprising two pivoted levers, gears on said 1eversintermeshing with each other, a spring acting on each lever, andconnections between said levers and said frame, said spring beingstressed by lowering of said frame.

6. A pin setting machine comprising a setter frame, means to lift saidframeand comprising a plurality of levers, intermeshing gears on saidlevers, connections between said levers and said frame, and a sprinconnected to each of said levers and stressed by lowering of said frame.

7. A pin setting machine com rising a setter frame, a handle connecte tosaid frame for lowering the same, a plurality of links connected to saidframe, a lever pivoted to each of said links and pivotally supportedabove said frame, and a spring connected to each of said levers andstressed by lowering of said frame.
